Abstract : Thermoelectric cooler (TEC) which uses Peltier effect to create heat flux across its sides has been of interest to researchers because of its compact size, precise control of temperature stability, and of quiet operation. TEC with 127 couples of volume 4 × 4 × 3.5 cu.cm is taken and its performance affecting parameters are analyzed. A comparative study is performed on various TEC models to obtain higher cooling capacity. Simulation is carried out by varying the geometry and the material used for the designed thermoelectric module. Results show cooling capacity has increased thrice with the decrease in leg height of TEC (linear square cross section, Bismuth Telluride) model from 0.3 to 0.1 cm. TEC model with circular cross section with the limiting taper angle 20° showed 50% decrease in its work input when compared with linear circular cross section legs. The Coefficient of Performance of the former model with Bismuth antimony as thermoelectric material showed 3.6 times higher value in comparison with Bismuth Telluride due to its figure of merit.
